Chelsea is graphing the function f(x) = 20()x. She begins by plotting the initial value. Which graph represents her first step?
Soloha48 [4]

we have the function

f(x)=20(\frac{1}{4})^{x}

we know that

In the equation of the exponential function of the form

f(x)=a(b)^{x}

a is the initial value

b is the base

x is the exponent

The initial value is the value of the function when the value of x is equal to zero

in this problem

for x=0

f(0)=20(\frac{1}{4})^{0}

f(0)=20(1)=20

the initial value is the point (0,20)

therefore

the answer in the attached figure

A line that is perpendicular to y=-3x-10 passing through the point (6,8)
Thepotemich [5.8K]

Answer: y = -1/3x + 10

Step-by-step explanation:

To make it perpendicular change the reciprocals

So instead of 3x it'll be -1/3x and so it passes through the given points

plug the points

8 = -1/3(6) + b

8 = -2 + b

add 2 to both sides

10 = b

so the equation of a line thats perpendicular to y=-3x-10 and passes through

points (6,8) is

y = -1/3x + 10
